I will assume that you have already learned how to use thermodynamics to study large systems, such as a gas or a learned how to use thermodynamics to study large systems, such as a gas or a liquid. To develop that theory we introduced work, heat, energy, entropy, and this development did we need to know that the system is made of molecules. this development did we need to know that the system is made of molecules. We invoked molecules occasionally, but their existence was never an essential part of the discussion. During the period in which the greatest developments in existence of molecules or dismissed the idea as an unnecessary hypothesis.
